See winterizing instructions at the end of this
section to prepare the toilet for storage in freezing

Further Information
See the toilet manufacturer's operation
information provided in your InfoCase for
complete operating, care, and maintenance
information.

DRAINAGE SYSTEM (P-TRAPS)

Ensure there is an adequate amount of water in
the drainage system p-traps to avoid sewer odor
from entering your coach.
If you should experience a sewer odor, pour
approximately 1 cup of water down each sink and
shower drain in the coach.
Washer/Dryer
–If Equipped
In addition to pouring water down sink and
shower drains, also run a wash cycle to ensure
there is an adequate amount of water in the
washer p-trap.

WASTE WATER SYSTEM

(Holding Tanks)
The drainage system is self-contained and
uses two separate holding tanks (or three,
depending on model) to contain the waste water
until it can be dumped at an appropriate waste
water disposal site. This means you can use the
toilet, sinks, and shower even in areas where
utility hookups are not available.
The black water holding tank contains the
sewage from the toilet(s) and may include
bathroom lavatory on some models. The gray
water holding tank(s) contain the waste water
from the galley sink and shower, and may include
bathroom lavatory.
See "Specifications" in Section 1 -
Introduction for tank capacities for your model.
Dumping Holding Tanks
The sewage drain hose (located in the water
service center) features a convenient handle and
valve nozzle for sanitary handling and improved
waste disposal.
1. Remove the dust cap from the sewage drain
outlet and connect the sewage drain hose. Be
sure it is firmly attached.
NOTE: The sewage drain outlet swivels
downward when necessary to avoid
bends in the sewage drain hose, which
could trap solids while dumping or to
provide more direct drainage while using
on-site sewer hook-ups.
2. Push the handle forward to open the sewage
drain hose end valve, then extend the hose and
place the nozzle into the disposal opening.
NOTE: The sewage drain hose end valve
(handle) must be opened before pulling
the hose to the disposal opening. If the
valve is closed, a vacuum will develop
and prevent the hose from expanding
fully.
Do not open holding tank waste valves
until the sewage drain hose end valve is
